HOME: Alejandro Mendoza arrives at JFK from Korea last night with Kristian and Haerin.NY Post: William C. Lopez

The New Jersey dad who battled for more than a year to get his two kids finally was reunited with them at JFK last night.

Alejandro Mendoza, 47, cried when he saw Kristian, 6, and Haerin, 3, for the first time since April 2009.

“My beautiful children are finally home,” the Dumont dad said. “All this time, I’ve been afraid I’d never see them again.”

Mendoza and his wife, violinist Si Nae-Shim, moved to South Korea after she got him a teaching job there. He returned when it didn’t work out, but Shim hid the kids with her mom. She defied a US court order to return them, complying only after she was arrested in Guam by US authorities.

A State Department official escorted them home.

When Mendoza last spoke with his son six months ago, he “begged me to come. I couldn’t, but we’re together now.”
